In the 2010 Energy Concept, the German government committed to reducing the primary energy requirement of buildings by 80% by 2050 and to increase the thermal retrofit rate from 0.8% to 2% per year. The 2% target is less than the 3%1 rate at which outer walls are currently being renovated each...

The German government has committed to reducing the primary energy demand of buildings by 80% by 2050. Achieving this reduction will require foremost efficiency improvements, with a first milestone of a 20% reduction in heat demand levels by 2020. Given that about 80% of today’s building stock...

Um Kosten, Energieimporte und CO2-Emissionen zu reduzieren, ist im Energiekonzept der Bundesregierung vorgesehen, den Wärmebedarf für Gebäude bis 2020 um 20 Prozent und den Primärenergiebedarf bis 2050 um 80 Prozent zu senken. Dazu soll der Anteil der jährlich energetisch sanierten Gebäude...

Executive Summary The German government aims to reduce primary energy demand by 80% until 2050 and heating demand by 20% until 2020. Besides the need for additional efforts to achieve these targets, Germany has already implemented a set of policies and programmes to increase investments in...

Buildings account for about 40% of the final energy consumed in Germany and arguably offer both low-cost and large scale energy efficiency improvement potentials. The Energy Performance Certificate (EPC) was recently introduced to capture this potential by providing information about the energy...

With increasing variability of demand and supply, transmission system operators (TSOs) across Europe adapt their internal processes and operational approaches. These processes comprise different interfaces with other market participants (e.g. via balancing markets, reserve procurement or NTC...

Long‐term energy contracts have featured prominently in many decisions of the European Commission to support the opening of the electricity markets. Contracts were seen to foreclose the market hence the Commission comprehensively unwound pre‐existing long‐term contracts and formulated...

Strategic reserves are in principle well suited to address both generation adequacy and system security in power markets. Depending on the power system and on the network topology, a strategic reserve has to be designed to fulfill both objectives. For the design of a strategic reserve (SR) in...

The EU European Trading Scheme (EU ETS) started operating in 2005 and was established with the EU Climate Package of 2008 as a permanent mechanism for Europe. Now in its second phase, policymakers are evaluating its success to date and considering next steps for its evolution. With the ultimate...
